' It will be understood'that' the"following description is more orless specificallydetailed to the disclosure appearing in the-present' drawings, and'is to be understood'in a descriptive rather than a limiting sense. Obvious'changes 1n the choice of material-employed, the Y elements forming the various parts of structure described, as Well as in the arrangement of the parts lnay be made Without departing from the spiritand full intend ed scope "oft'he invention. i

1 Referringnow by reference numerals-to the drawings, the table, or-supporting portion of the structure, consists 'of a frame constituted O by a pairof end rails 5*and 6 constru'cted preferably of WOOCl "and correspondingly socketed on their inner faces to receive a pair ofs ide rails T and8. The side'rails are preferably of circular cross: section, for spurposes hereinafter appearing, and may be glued as by waterproof glue, or otherwise secured into the appropriate sockets therefor in the rails 5 and 6. Also extending between the end rails 5 and 6, on the side most remote from the operator, is an auxiliary brace rail 9 which serves endwise to strengthen the rails 5 and 6, the brace ra l extending between their free ends which project inwardly beyond the supporting surface proper as will appear, and serve normally as horizontal leg portions.

The supporting surface is, by preference, formed of a canvas cover 10, or like washable flexible material, and which, by further preference, is secured only at its sides. The innermost side of the canvas cover is secured to the round side rail 8, and extends transversely of the table, toward the operator and into engagement with the rail 7. The rails 7 and 8, to the end of engagin and stretching the canvas cover 10, are provided with a plurality of fasteners 11, in register with each of which is a groinet 12 in the cover. It is pre ferred to construct the fasteners 11, as well as the groniets, of such metal, or so plated, as to be rendered rust proof.

Intermediate the sides and ends of the cover 10 are a plurality of apertures 13, for purpose of drainage as the infant is being washed, showerbathed or rinsed. The apertures 13 are, by preference, provided with groinets 14: so as to prevent any tendency of the fabric to unravel where it is perforated. If desired, the end portions of-the canvas cover may be provided with a pair or more of apertures provided with gromcts as shown at 15, for the purpose of inserting a draw string or he equivalent for keeping the vas cover taut, as it may tend to loosen under the influence of repeated use and application of moisture.

As will hereinafter more fully appear from the description and use of the present table, it is my preference to provide an auxiliary cover 16, which in the present instance would be constructed of rectangular shape and correspond snbstantially to the effective area of the cover 10. The cover 16 is, by preference, formed of a water tight or waterproof, nonabsorbent material such as rubber sheeting, and may be secured in place as by glove fasteners 17, there being one of such fasteners disposed at each corner of the working surface of the cover 10.

Depending from and, by preference, form-- ing a part of the cover 10, is an overhanging or tab portion 18 presented laterally so as to hang vertically on the side of the table nearest the operator. This tab portion may be formed of such width and length as to be folded upon itself, the folds being sewed to the main body of the tab in a manner to form a plurality of pockets 19, each shown as opening at the top and affording convenient reample as towel racks or handles by which to support the table when setting it up, there are provided, one on each of the end rails 5 and 6, U-shaped extensions 20 and 21. These members are, by preference, formed of metal and, like other metal parts of the structure,

preferably formed or processed to resist rusting. It will readily appear that the auxiliary brace rail 9 may also be employed for lifting purposes, or as a rack for garments, towels and the like.

The description thus far has related to the horizontal supporting portion of the structure by way of describing its component parts. The sub-structure consists of a pair of legs of substantially A shape, each of which is pivotally secured at its upper end to one of the end rails 5 or 6 as by a through pin 24:, this pivot being disposed by preference substantially nearer the operators side of the table. The opposite, or lower ends of the legs 22 and 23 are shown as bifurcated, being arcuately recessed to correspond in curvature to, and for the purpose of engaging, the longitudinal hand rail of bath tubs of usual type and proportions. It will be seen that the legs 22 and 23 thus engage the opposite sides of the hand rail of the tub in a manner effectively to prevent movement of the table structure laterally or transversely of the tub when employed therewith. Extending lengthwise of the table and between the lower portions of the legs 22 and 23 is a brace 25, preferably of circular section and having at each end a shoulder (not shown) to receive at a point just inside of each of the legs 22 and 23, strut members 26 and 27, one at each end of the table.

The struts are adapted to extend inwardly across the tub and upwardly therefrom (Figs. 1 and 3) to engage in supporting relation the inner ends of the rails 5 and 6. For this purpose and to enable selectively locating the point of connection between the struts 26 and 27 and rails 5 and 6, I have provided at the outer end of each strut a pivotally supported clamp, consisting of a pair of clamping jaws normally resiliently urged toward open position, and adapted to be actuated toward closed position by a lever-operated cam pivoted to the outermost clamping jaw, all of which will clearly appear from Fig. at. One of such clamping devices is shown generally at 28. For engagement by the clamps, each of the rails 5 and 6 is provided, as an extension from its under surface, a beaded portion 30 which may be formed as an integral part of each rail, or made separately and secured thereto.

For purposes of assembling and strengthening the supporting structure endwise and and 23, and the wood screw being taken into the end section ofthe brace 25, at each end. The rigidity of the leg structure, particularly the portion constituted by struts 26 and 2?,

may be increased by employing an auxiliary brace 33 extending lengthwise of the structure and between substantially intermediate portions of the struts 26 and 27 As will appear from Fig. 1, the dressing and shower table of the present invention is adapted for primary support on the outermost longitudinal hand rail of the usual bath tub of adult size, auxiliary support being derived by abutting and frictional engagement of the free extremities of rails 5 and 6, with a substantially vertical wall surface.

It is of course desirable to enhance the frictionalengagement at these points as far as practical. To this end and to avoid. any tendency to mar the wall surface, I provide friction elements 34, formed say'of rubber, and

which may be secured as by a wood screw directly to the ends of therails 5 and 6.

The manner of folding the described table from its normal position of use, and vice versa, the operation of extending it for use from its folded position, are thought to be fully apparent from the preceding descriptionof parts and their relation, but may be briefly referred to for sake of completeness. Considering the tablein its set-up position as shown in Fig. 1, and desiring it to be folded, the clamps 28 arereleased as by lifting the clamp handles, thus freeing the ends of struts 26 and 27, after which the leg assembly including legs 22 and 23, brace 25, .the struts, etc. may be rotated as a unit, in a counter clockwise direction (Fig. 3) about the pivots 24. Such rotation is carried through substantially three-fourths of a revolutic-n, or until the legs 22 and 23 are brought into substantial parallelism with the rails 5 and 6, with the brace 25 substantially overlying the side rail 9. The struts 26 and 27 being free to rotate about the brace 25, are further rotated in the opposite direction, into substantial parallelism with the legs 22 and 23 and hence also with the end rails 5 and 6, after which the table lies substantially flat, (Fig. 2), so as'to occupy a minimum'space enabling it to be readily stored or compactly containedpending future use When the table is folded the clamps 28 may be rotated about their pivots to the position shown in Fig.2, and clampingly actuated to engage adjacent projections 29 on the end rails, thus effectively securing the device. in folded po sition.

.While the operation of folding the table has been described by' reference to a movement of the leg structure relative'to the normally horizontal supportin or table portion, the leg structure may ohviously be kept stationary and the table portion rotated within andbetween the legs 22 and 23 to produce the same result. An advantage, upon folding, will be observed when it is considered that upon rotatin the parts of the table into folded relation, the tab 18 forming pockets 19 will'be' brought, usually without separate effort, to such position that it immediately overlies the upper working surface of the table, for example the cover 10, the parts being in such relation that the pockets 19 fallbetweenthetablS and the cover 10 in a manner to conceal and protect the contents of the pockets.

It will appear from the preceding description of parts and arrangement of the device that it has been designed throughout with a View of combining maximum adaptability and utility with a. structure of unusually light weight and compactness. The device of the present showinghas been constructed as a bathing and dressing table for infants and children weighing up to thirty-five pounds. On this basis, the device provides a safety factor of at least four, being ample to support without danger of breakage the weight of the normal adult of 140 to 150 pounds. I

' The provision of a flexible supporting surface consisting primarily of the canvas cover 10, has been found to be of particular advantage in that itenables ready replacement and laundering of this element. The provision of a. cover of double thickness, the thick nesses thereof consisting respectively of the cover 10 and the auxiliary cover 16 which may be of rubber, will be noted as of obvious advantage inthat, for purposes of bathing, the rubbercover may be removed or rolled to occupy only one edge of the operating surface. During the process of bathing, the canvas cover 10 will be, of course, depressed somewhat by the weight of the infant so as to bring one or more of the drainage apertures'13 near the lowest portions of the cover, which provision renders the table convenient as a support for shower bathing purposes. The provision of the auxiliary cover 16 of waterproof material, provides a surface which may be kept dry and laid over the previously moistened cover, so that the infant may be dried and dressed on the same support, to the end of minimizing lifting and transfer steps.

"The recited provision for supporting the table primarily from the outside hand rail of .thetub and by a vertical wall portion on the opposite side of the tub, has been found to be "ofparticular utility, since in some instances the inner side of the tub may be embedded in the wall and consequently not available for supporting :a'table having the usual legs on its opposite sides.
